@antonioklix we will need to know the complete model number for your Element TV.
Make sure that you are plugged into a working power outlet. Then check the power cord and make sure it is properly connected. Next you will need to tell us if the Power LED lights up at all.
If not, then it is absolutely possible that thi is a power board issue. Might just be a bad fuse but cold be lots of other things. I would suggest to unplug the TV, remove the power cord and remove the back cover. Then take a look at all the boards and check for anything damaged/scorched/missing components. Take some good pictures of all of your boards and post those with your Question. That way we can see what you see nd hopefully guide you further. Here is the guide for that [guide|21499]
